Initialize debug agent.
This function is used to set up debug environment to support source level debugging.
If certain Debug Agent Library instance has to save some private data in the stack,
this function must work on the mode that doesn't return to the caller, then
the caller needs to wrap up all rest of logic after InitializeDebugAgent() into one
function and pass it into InitializeDebugAgent(). InitializeDebugAgent() is
responsible to invoke the passing-in function at the end of InitializeDebugAgent().
If the parameter Function is not NULL, Debug Agent Library instance will invoke it by
passing in the Context to be its parameter.
If Function() is NULL, Debug Agent Library instance will return after setup debug
environment.
@param[in] InitFlag Init flag is used to decide the initialize process.
@param[in] Context Context needed according to InitFlag; it was optional.
@param[in] Function Continue function called by debug agent library; it was
optional.
